Description
Technical field
The utility model relates to a kind of melt spinning assembly that is used to produce synthetic fiber.
Background technology
The synthetic fiber that melt spinning obtains are widely used in every field such as clothes and industrial materials because of having favorable mechanical and chemical property.In melt spinning apparatus, generally include screw extruder, measuring pump, spinning manifold, filament spinning component and blowing device etc., polymer from the spinneret orifice ejection, forms fiber after tow is cooled after being transported to by screw extruder and after the measuring pump metering and filtering in the filament spinning component.Filament spinning component is important equipment in the polyester fondant spinning equipment.At present the polyester fondant filament spinning component all adopts the plane screen pack or adorned filter sand peace face screen pack and be used for reaching the purpose of elimination polyester fondant impurity.At traditional dress the polyester fondant filament spinning component of filter sand peace face screen pack and usefulness, comprise a circle tube assembly housing, a spinnerets with many polyester fondant pod apertures, number of metal silk screen filter part, the cylindric spacer that filter medium is housed, a particle filtration bed and a module cover that is contained in spacer inside, above-mentioned parts are exactly to be installed in respectively in the polyester fondant filament spinning component housing with this order from bottom to top.In the said structure filament spinning component, at first, the polyester fondant particle filtration bed of flowing through is distributed in its central area thick and fast, and unlikely reaches the neighboring area, and the silk that is obtained by a plurality of spinneret orifices of spinnerets is in difference and to produce fiber number inhomogeneous to some extent each other aspect the filament diameter.Secondly, have an appointment 40% void volume of particle filtration bed accessory, prolonged the time of staying of polyester fondant in the particle filtration bed, the easy part of polyester fondant causes unusual stop, rotten, make will become irregular by the spun silk of spinnerets character longitudinally, the fiber number of silk is inhomogeneous, influences fiber quality, broken end appears in serious meeting in spinning process, make the spinnability variation.The 3rd, melt enters the hole through the polyester fondant that is arranged on the module cover center and flow into the particle filtration bed, and the filter area of this filter bed is a circle, and filter area is very limited, directly has influence on the life cycle of assembly.
Summary of the invention
Technical problem to be solved in the utility model is by traditional spinning component structure being improved, the filter area of filament spinning component is increased, and to improve filament spinning component service life, reduces its production cost.The time of staying of polyester fondant in assembly shortened, improve the quality and the spinnability of tow.
The utility model is achieved through the following technical solutions.
A kind of melt spinning assembly that is used to produce synthetic fiber, comprise at the bottom of one and the uncovered assembly housing of top surface, spinnerets that is arranged on foot in the assembly housing with many spinneret orifices, a center that is arranged on topmost in the assembly housing has the upper cover plate that polymer melt enters the hole, three-dimensional filter element is housed between upper cover plate and spinnerets, this filter element comprises chin spoiler, the annular filter post, an annular filter post is housed between baffle upper plate and chin spoiler at least, described going up on the chin spoiler has flow-guiding channel, flow-guiding channel and annular filter post on the baffle upper plate, flow-guiding channel communicates on the chin spoiler.
In order to improve the flowability of melt in the annular filter band of column, set up a support column in the chin spoiler central area, described support column is packed in the ring of annular filter post and is coincide with baffle upper plate, baffle upper plate basal surface, support column outer surface, annular filter post medial surface and chin spoiler upper surface form second space, and baffle upper plate basal surface, annular filter post lateral surface, assembly housing inwall and chin spoiler upper surface form the 3rd space.
In order to make annular filter post inner filtration chamber melt volume reach optimum, and be beneficial to flowing of polyester fondant, the annular filter post can be made up of with two different inner filtration circle, outer sphere filter and columns of diameter upper press ring, following pressure ring, two sphere filters are embedded between upper press ring and the following pressure ring, form filter chamber between upper press ring, following pressure ring, inner filtration circle and the outer sphere filter, the column of a plurality of adjusting melt amounts can be installed in this filter chamber at interval.
In order to reduce the time of staying of polyester fondant in filament spinning component, make melt-flow through the time of staying of assembly basically identical, the ratio of pod apertures area summation equals the ratio of inner filtration circle filter area and outer sphere filter filter area outside pod apertures area summation and the baffle upper plate in baffle upper plate.
Compared with prior art, the utility model is because of having adopted three-dimensional filtration, overcome the defective that traditional polyester fondant filament spinning component filter area causes for a short time, because filter area increases and shortens the time of staying of polyester fondant in filament spinning component, thereby prolonged filament spinning component service life, save production cost simultaneously, improved the quality and the spinnability of product.
